SPECIFICATION forming part of Letters Patent No. 688,390, dated December10, 1901.

Application filed February 4, 1901. Serial No. 45,883. (No model.) i

and useful Improvements in Sectional Bookcases, of which the followingis a specification. The present invention is in the nature of somespecific improvements in the lines of the invention shown and claimed inmy application forsectional bookcases, Serial No. 45,290, filed January30, 1901.

The improvements consist, essentially, in a novel and useful equalizingdevice for preventing the sliding door from binding and in certain othernovel features of construction, all of which Will be hereinafter fullydescribed, and finally embraced in the clauses of the claim.

Referring to the drawings, Figure 1 is a transverse section of a caseprovided with my improvement. Fig. 2 is a plan view of the same, showingthe door partially pulled out of the case. Fig. 3 is a front view ofthe. case with the door removed. 1

Similar letters refer to similar parts throughout the several views. o

A represents the bottom,'B the back, and O the sides or ends, of thecase. In practice severalcases of this kind are placed one on top of theother and are provided with removable top and base sections, all ofwhich interlock with one another.

D represents an adjustable supporting device for the bottom of thecase,and which consists of a rod having one end secured to the centralportion of the bottom adjacent to its front edge, the other or rear endof the rod being adjustably secured in the upper portion of the back ofthe case by means of a nut D, the said rear end of the rod being forthat purpose provided with screw threads D The front end of the rod ispreferably provided with an enlarged portion or head D which engages theunder side of the bottom of the case. It-will be seen that thissupporting-rod prevents the central portion of the shelf or bottom ofthe case from sagging when books or other objects are placed upon sameand makes the case more rigid. While I have shown the rod provided withanut at one end for the purpose of adjusting or tightening the rod, itis evident that same may be adjusted by some other means.

E represents adoor, which is pivotally mounted in the front portion ofthe case by means of a, hook E, which engages stops F.

When brought to a horizontal position, thisdoor slides into the caseupon rails G, secured to the sides or ends of the case. These rails areprovided with felt cushions G on their upper or supporting edges, andwhich cushions cause the door to slide into the case noiselessly.

H represents an equalizer for the door, comprising two levers or armswhich cross each other. One of these arms has a slot H at its center,and which slot is adapted to receive and form a bearing for a stud orbutton H which is permanently-secured to the other arm, the above slotbeing slightly curved, so as to conform with the path taken by the saidpin H when the arms close or open. The forward end portions of the armshave reduced inwardly-curved portions, which are slidably mounted ineyelets I, secured on the door E,

the rear ends of the arms being pivotally connected to the back of thecase bymeans of hooks or stationary pivots J, which engage holes oropenings in the said ends of the arms.

The operation of the equalizer is as follows: When the arms close, theforward end portion of same slides outwardly in the eyelets or bearingsprovided therefor, the pin moving in the guide channel or slot 11',causinga perfect uniform movement of the arms. The door,which isattached thereto,will thus move steadily in a straight path in and outof the case without binding. I

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

1. A case or crate having a slidable door or drawer, an equalizer forsaid door comprising two arms which cross each other, one of said armsbeing provided at its central'portion with a curved guideslot orchannel, the other arm having a pin or buttonadapted to move drawer, anequalizer for said door comprising ing an open front, a supportingdevice for the two arms which cross each other, one of said bottom ofsaid case comprising a rod extendarms being provided at its centralportion I ing in an inclined direction from the back to with a curvedguide slot or channel, the other near the front edge of the bottom,means for 15 5 arm having a pin or button adapted to move adjusting thetension of said rod substanin said channel, the forward ends of the armstially as described.
